I present and defend a reliabilist explanation of a priori knowledge which fulfils seven plausibility requirements.

> Context • The alleged dichotomy between mind and matter is pervasive. Therefore, the attempt to explain mat- ter in terms of mind (idealism) is often considered a mirror image of that of explaining mind in terms of mat- ter (mainstream physicalism), in the sense of being structurally equivalent despite being reversely arranged. > Problem • I argue that this is an error arising from language artifacts, for dichotomies must reside in the same level of abstraction. > Method • I (...) show that, because matter outside mind is not an empirical observation but rather an explanatory model, the epistemic symmetry between the two is broken. Consequently, matter and mind cannot reside in the same level of abstraction. > Results • It then becomes clear that attempting to explain mind in terms of matter is epistemically more costly than attempting to explain matter in terms of mind. > Implications • The qualities of experience are suggested to be not only epistemically, but also ontologically primary. > Constructivist content • I high- light the primacy of perceptual constructs over explanatory abstraction on both epistemic and ontic levels. > Key words • Idealism, physicalism, pancomputationalism, anti-realism, hard problem of consciousness, epistemic symmetry, explanatory abstraction, levels of abstraction.

Este ensaio consiste num exame crítico da estrutura e do valor de um conjunto diverso de argumentos por regressão ao infinito que têm sido objecto de discussão recorrente na metafísica contemporânea. O seminal livro de David Armstrong Nominalism and Realism (Armstrong 1978) contém uma das mais compreensivas discussões de argumentos regressivos em metafísica, os quais variam entre argumentos que foram de facto avançados ao longo da história da disciplina (como o Argumento do Terceiro Homem, de Platão) e argumentos construídos de (...) novo por Armstrong para fins de exame crítico. Os argumentos regressivos discutidos por Armstrong têm como alvo uma grande variedade de teorias metafísicas acerca da semelhança e da predicação, entre as quais se contam o nominalismo de predicados, o nominalismo de conceitos, o nominalismo de classes, o nominalismo de semelhança e o realismo metafísico.

In the Twentieth Century, Logic and Philosophy of Language are two of the few areas of philosophy in which philosophers made indisputable progress. For example, even now many of the foremost living ethicists present their theories as somewhat more explicit versions of the ideas of Kant, Mill, or Aristotle. In contrast, it would be patently absurd for a contemporary philosopher of language or logician to think of herself as working in the shadow of any figure who died before the Twentieth (...) Century began. Advances in these disciplines make even the most unaccomplished of its practitioners vastly more sophisticated than Kant. There were previous periods in which the problems of language and logic were studied extensively (e.g. the medieval period). But from the perspective of the progress made in the last 120 years, previous work is at most a source of interesting data or occasional insight. All systematic theorizing about content that meets contemporary standards of rigor has been done subsequently. (shrink)

Thinking and using a language are two different but similar activities. Thinking about thinking and thinking about language use have been two major strands in the history of philosophy. One of the principal similarities is that they are both rational activities. As a result, the ability to think and the ability to use a language require being able to recognise and respond to reasons. However, there is a further feature of these activities: we humans are able to have explicit knowledge (...) of how those activities work and what is done by performances in those activities. Thus, theorists face at least two constraints: 1. An account of a rational activity must be compatible with the possibility of agents engaging in that activity. 2. Having described an activity, it must be possible to have knowledge of an activity which is correctly described like that. There are a variety of accounts of how thinking works and how using a language works, and further variation in accounts of what is involved in explicit understanding of particular performances. These accounts can be distinguished by their views of the nature of the reasons that govern performances in that activity and by their views of the way a description of the activity relates to the way the activity proceeds. I argue that any description of thinking or language use requires showing how the truth conditions of thoughts/sentences are determined, and how the truth values of thoughts/sentences affects the way the activity proceeds. I then argue that in order to have explicit knowledge of what we do, truth has to be a substantial evaluative property of uses of language, and furthermore a truth conditional theory of meaning has to be taken as the description of the rationality of using a language. The big result is that, because in understanding language we understand truth, the philosophy of language is first philosophy. (shrink)

The paper outlines the model of controversy spaces. The model of controversy spaces integrates two different elements of the dialectical tradition. On the one hand, dialectics in its ancient meaning: the practice of controversial dialogue. On the other hand, the model incorporates dialectics understood as a pattern of change in intellectual history, based on the confrontation between opposite standpoints. I will be argued in this paper, the dialectical tradition was almost completely left aside in modernity and substituted by a monolectic (...) approach. The model that will be outlined below aims at overcoming this view by focusing on the emergence, development and transformation of controversy spaces. (shrink)

In order to understand consciousness one would benefit from developing a more eclectic intellectual style. Consciousness is, as proposed by almost everyone except the stubborn reductionists, a truly mysterious concept. Its study and dissection merits a multidisciplinary approach. Waving this multidisciplinary flag has positively enlarged the discussion and neurologists, psychiatrists, mathematicians, and so on, have moved to the philosophy of mind arena, first with caution and now with a more powerful voice. Identifying what we mean by consciousness is a first (...) step even when we want to deny its existence. The link between consciousness and some other mental activity is a logical next step and there is abundant literature doing this, but not all of them differentiate among associated yet different phenomena.

William James has been characterized as “the major whipping boy of the later Wittgenstein,” and the currency of this impression of the relation between James and Wittgenstein is understandable. Reading Wittgenstein and his commentators can leave one with the impression that James was a badly muddled “exponent of the tradition in the philosophy of mind that [Wittgenstein] was opposing.” There have been recent attempts to resist this trend, but even these tend to focus on the affinities between the two philosophers, (...) still accepting the prevailing view that Wittgenstein was often critical of James, and that in such cases Wittgenstein was always right and James was always wrong. By contrast, by focusing on Wittgenstein’s discussion of James’s “if-feeling”, it will be argued that Wittgenstein’s criticisms of James are often not as damaging, or even as extensive, as has often been assumed. /// -/- NB: This was essentially an initial draft of the paper that became "William James on Conceptions and Private Language", which should also be available for download in the publications section of this page.

On the assumption that we may learn from our elders and betters, this paper approaches some fundamental questions in perceptual epistemology through a dispute between McDowell and Wright about external world scepticism.

This paper explores the possibility of building a coherent knowledge base for philosophyof design in IS research. After identifying and categorizing what is considered as designissues in the IS field, we propose a taxonomy of design abstractions in the form of a meta-theoretical structure. Based on the proposed hierarchical taxonomy, we have conducteda concept-centric literature review on four leading IS research journals publishedbetween January 2011 and July 2016. Our result shows that the IS field struggles withmisalignment of philosophy of design (...) issues, including constructing design theory,research positioning, and an inconsistent knowledge base in design subject areas such asethics and aesthetics. It is suggested that integrating philosophy of design into IS researchcould contribute to the development of a coherent body of design knowledge. We concludeby proposing a model both to study and integrate philosophy of design into the ISresearch field. (shrink)

Violence dominates the landscape of our present world. Prejudice and sectarianism threaten human rights, putting our hopes for the authentic possibility of humane ethical/moral interaction on a global scale in serious question. Ours is a world where epistemological and ethical relativism appear to rule the day. In these extremely “hard times,” as Nietzsche was fond of saying, it would benefit us, as philosophers, informed thinkers, and concerned human beings, to revisit with a discerning eye and charitable heart the philosophy of (...) Bertrand Russell as it appears in The Problems of Philosophy (1912), wherein Russell reminds us in a powerfully persuasive manner just how important philosophy can be in offering hope for a better world during dark, turbulent times. In this paper is an examination of the unique way in which Russell responds to the following question: What is philosophy good for, what is the value of philosophy for the world and its inhabitants?

[1] Imagine a well-trained mid-century American philosopher, caught in a rare traffic jam on the New Jersey Turnpike one warm summer afternoon in the early 1950s. He dozes in his warm car ... and awakes in the same spot on a chill Fall evening in the late 1990s, remembering nothing of the intervening years. It is as if he has been asleep at the wheel for almost half a century!

According to the standard view, the causal process connecting a past representation and its subsequent recall involves intermediary memory traces. Yet Bertrand Russell and Ludwig Wittgenstein held that since the physiological evidence for memory traces isn't quite conclusive, it is prudent to come up with an account of memory causation-referred to as nmemic causation—that manages without the stipulation of memory traces. Given mnemic causation, a past representation is directly causally active over a temporal distance. I argue that the stipulation of (...) memory traces is indeed indispensable for analyzing mernory causation. (shrink)

Theories of cognition and theories of social practices and institutions have often each separately acknowledged the relevance of the other; but seldom have there been consistent and sustained attempts to synthesize these two areas within one explanatory framework. This is precisely what my dissertation aims to remedy. I propose that certain recent developments and themes in philosophy of mind and cognitive science, when understood in the right way, can explain the emergence and dynamics of social practices and institutions. Likewise, the (...) view I construct explains how social practices and institutions shape the character of cognition of their constituent agents. Moreover, I explain both cognitive and social agency under the single explanatory framework provided by Dynamic Systems Theory. Drawing upon the phenomenological tradition, "embodied, "extended", "embedded", "enactive", and "ecological" approaches to cognition, as well as the conceptual resources of Dynamic Systems Theory, I construct a theory of agency that sees cognitive and social agents as far-from-equilibrium, open, recursively self-maintenant dynamic systems. Depending on the specifics of concrete circumstances, such systems, which I call "Dynamic Embodied Agents", may develop and possess emergent capacities for error-detection, flexible learning, normative behavior, representation, self-reflection, various modes of pattern-recognition, a temporal sense of self, and even moral responsibility. Some such systems are also sensitive to perceived social influences ; while reciprocally constituting and causally affecting them. (shrink)

Many of our ordinary beliefs about the world around us are a result of inference from more fundamental beliefs. Foundationalists in epistemology have thought that, if these ordinary beliefs are to be rationally justified, the chain of inferential justification must terminate in a belief that is justified noninferentially. Foundationalists, of the internalist variety, have thought that the most plausible candidates for ending the regress of empirical justification are experiential states, the justifying features of which the believing subject is aware. The (...) Sellarsian dilemma, taking its name from philosopher Wilfrid Sellars, has been a persistent argument against foundationalist theories of epistemic justification. There have been various formulations of the dilemma over the years, but in its most general form it says that for any construal of an experiential state where the experiential state provides justification, the experiential state will need further justification. Sellars thought that an experience, all by itself, cannot provide justification unless we apply concepts to the experience. However, the application of concepts is judgmental and conceptual judgments, like beliefs, require further justification. So, the experiential state construed this way would perpetuate the regress it was designed to terminate. On the other hand, if the experiential state is construed such that it is not in need of justification, then it cannot itself provide justification. Both options are devastating to a foundationalist epistemology. My thesis is that a solution to all forms of the Sellarsian dilemma is to require for foundational justification direct awareness of the fit between one's conceptual judgment and the justifying experiential state. I concede that one must conceptualize one's experiential states for these states to play an epistemic role. However, I argue that conceptual judgments of this sort are the foundations. The importance of this solution is that it not only terminates the regress of justification but it also captures the primary intuitions that motivate internalism and foundationalism. This is to say that although I have framed my account as a response to the Sellarsian dilemma, it is not merely an ad hoc patch that avoids what stood as a serious problem. Instead, it is a return to what has motivated and what I take to be most persuasive about internalist foundationalism. (shrink)

Various logic texts offer explanations of a fallacy identified as an appeal to tradition. The identification of this fallacy should be scrutinized for any faulty reasoning. Whether this fallacy is committed depends on the kind of relation asserted be tween the present and the past. An understanding of its relations clarifies when an appeal to tradition could be fallacious. This is illustrated by the views of Socrates, Bentham, Scruton, and others. I argue tradition transfers something from the past to the (...) present. Whether the transfer is fallacious depends on what and how something is transferred. (shrink)

This essay purports to be a “negative” defense of acquaintance foundationalism. It is “negative” in that I do not do much in the way of advancing novel argument for the position, nor do I extend the position very much. Rather, I focus on demonstrating that the position has the resources to overcome objections that have been proposed to it. In particular, I argue that it can overcome the dilemma proposed by Wilfrid Sellars and developed by Laurence BonJour against foundationalism, as (...) well as dilemmas proposed by Jack Lyons and Michael Bergmann targeting internalism. Acquaintance foundationalism is what I will call any theory of justification that is internalist in what may justify us, foundationalist in the structure of justification, and relies on the concept of acquaintance in justifying our basic beliefs. Internalism requires that what justifies us improves the belief from the perspective of the believing subject. Foundationalism states that the justification for all beliefs depends ultimately on basic beliefs. Finally, acquaintance is a relation between a person and other things such that these other things are before the “mind’s eye” of the subject. The general idea behind each of these dilemmas, so I will argue, is to claim that acquaintance foundationalism cannot provide epistemic reasons for basic beliefs, where epistemic reason means something that contributes to justification from the subject’s perspective. Each dilemma will ask whether the alleged justifier has some feature x. However, each dilemma contends that, whether the alleged has the feature x or not, it cannot serve as an epistemic reason. For example, BonJour will ask whether our allegedly basic beliefs are cognitive or not. He argues that if they are cognitive, they need justification, but if they are not cognitive, they cannot provide justification. Thus, no allegedly basic belief can serve as an epistemic reason. I argue that the notion of acquaintance allows us to escape such dilemmas because our states of acquaintance allow us to justify our basic beliefs without requiring justification themselves. I do so by borrowing, in part, Richard Fumerton’s theory of non-inferential justification, plus adding on a few epicycles to allow us to base our basic beliefs on our acquaintances. The first chapter sets up the issues of the dissertation: it gives context to the project, defines acquaintance foundationalism and epistemic reason, and discusses our dilemmas in broad outline. It also summarizes the rest of the essay. I use epistemic reasons in a specialized sense in the dissertation, which necessitates an extended discussion. This is the focus of chapter two. I argue that an epistemic reason is a mental complex that consists of Fumertonian acquaintances. When we have an epistemic reason, we have a mental complex that is related in the appropriate way to a belief. This is just what provides justification for the belief. This chapter explicates this notion. It includes an extended discussion of Richard Fumerton’s theory of non-inferential justification, which I follow in outline but diverge from in detail. This discussion focuses on his notion of acquaintance, and the items with which we may be acquainted. I then move to a discussion of the metaphysics of epistemic reasons, explaining how they consist of these acquaintances. I also discuss the relationship between epistemic reasons and epistemic justification. The third chapter is historical in focus. I examine Sellars’s famous dilemma for foundationalism, and contend that it can be best understood as an attempt to deny the foundationalist epistemic reasons for his beliefs. I also examine Laurence BonJour’s later formulation of the Sellarsian dilemma, and again argue that it is best understood as denying epistemic reasons to foundationalists. I then review the options that an acquaintance foundationalist has to respond to these dilemmas, as these responses will allow us to see where our more recent dilemmas go wrong. Chapter four address Jack Lyons’s dilemma. I consider what Lyons says about his dilemma at some length. I then argue that it is structurally similar to the Sellarsian dilemma, and tries to undermine the internalist’s ability to offer epistemic reasons for his beliefs. I then argue that Lyons’s dilemma only seems persuasive because he misunderstands what is required for experience to provide us with an epistemic reason. When properly understood, his dilemma fails to tell against the acquaintance foundationalism. I also argue that Lyons’s version of externalism is much more radical than it might initially appear, helping to motivate acquaintance foundationalism. The fifth chapter focuses on Michael Bergmann. I give his dilemma an extended discussion, which I follow up by reframing it in terms of epistemic reasons. I argue that his dilemma, while seemingly persuasive, fails to trouble the acquaintance foundationalism. I argue that we may be strongly aware of our epistemic reasons without starting a regress, which vitiates his dilemma. I conclude with some short remarks on possibility of skepticism. (shrink)

Traditional philosophy has been under attack from several quarters in recent years. The traditional philosopher views philosophy as an armchair discipline relying, for the most part, on reason and reflection. Some philosophers doubt the legitimacy of this type of inquiry. Their arguments usually occur along two dimensions. Some argue that the primary data source for the armchair philosopher--intuition--does not provide evidence for philosophical theories. Others argue that conceptual analysis, which is the preferred method of inquiry for armchair philosophers, can't yield (...) the results the philosopher is looking for, since concepts like 'knowledge' or 'free-will' vary from culture to culture or even between persons within a culture. Finally, some philosophers argue that we should abandon the armchair program because philosophy should be an empirical enterprise continuous with the sciences. I argue that attempts to undermine intuition fail and that one can justify the evidential status of intuition in a non-question begging way. I then argue that attacks on the belief in shared concepts do not succeed because they often conflate the nature of scientific objects with those of interest to the philosopher. However, if concepts do vary from culture to culture, I show that the philosopher need not abandon the armchair. She can still do conceptual analysis but it will be only the entry point into the philosophical dialogue. I apply this approach to epistemology arguing that the central epistemic questions ought to be the existential and the normative. This approach helps to vindicate epistemic internalism. (shrink)

In this paper I examine critically the relationship between the realist and nominalist views of abstract objects. I begin by pointing out some differences between the usage of existential statements in metaphysics and the usage of such statements in disciplines outside of philosophy. Then I propose an account of existence that captures the characteristic intuitions underlying the latter kind of usage. This account implies that abstract object existence claims are not as ontologically extravagant as they seem, and that such claims (...) are immune to certain standard nominalistic criticisms.
